Aapplication le November 16, 1912. Serial` No. 731,743.

To all whom it may concern:

Be it known that ll, WILLIAM H'. GOEDEN, a citizen of the United States, residing at Nebraska City, in the county of @toe and State of Nebraska, have inventedneu7 and useful mprovements vin Door-Locks, ot which the following is a specification.

This invention isan improved automatic door lock adapted to be locked or unlocked from the inner side of the door on Which it is placed and Without the use of a key and especially adapted to be locked by the hanging of one or more articles ofclothing o-n a hook lever which forms an element of the bolt operating mechanism, the object of the invention being to provide an improved lock orI this character which can only be operated from the inside of the door on which it is placed, which dispenses with the use ci a key, which cannot be opened by a burglar on the outside ot the doorand which is adapted to be automatically set in locking position by the hanging oit one or more articles of clothing or other objects on the hook lever which forms an element or its bolt operating mechanism.

W ith the above and other objects in View,

the invention consists in the construction, combination and arrangement ot devices -hereinafter described and claimed.

Tn the accompanying drawings lTigure 1 is an elevation oitJ a lock constructed in accordance with my invention, showing a pon tion ci a door on Which the lock is mounted and also showing a portion of the door cas- Fig. 2 is a vertical longitudinal sectional -view of the same with the parts in unlocked position. llig. 3 is a similar view, showing the parts in locked position. Fig. el is a vertical transverse sectional View on the plane. indicated by the line d-d or 'll-lig. 1.

For the purposes o this specification, a portion oi a door is indicated at 1 and a door casing at 2. The casing is shown as provided at one side with a suitable keeper 3. My improved lock has a base plate l secured on the inner side ofthe door by means orn screws or other suitable devices and a casing 5, the bottom of which is formed by a base plate, the casing being here shown as provided with lugs 6 `which bear on the base, plate and are secured thereto by means of screws 'i' which pass y through openings in the base plate and enter the door. The base plate has a longitudinal slot 8 at the inner end of which is a guide 9. A guide 10 is at the outer end of the base plate. A longitudinally movable bolt 11 is provided which operates in the guide, is adapted to engage the keeper When the do-or is closed and is provided with a rod 12 which projects from its inner end, the said rod operating in an opening in the guide 9. A coiled spring 13 to normally hold the bolt in unlocked position is arranged on the bolt rod 12 and in the slot 8, one end of the said spring bearing against the guide 9 and the other end thereof bearing against a stop pin 14 with Which the bolt rod is provi-ded. At the outer end of the casing is an opening 15 through Which the outer end of the bolt rod extends. Said bolt rod has a notch 16 near its outer end and on its inner side and a dog 17 is pivotally mounted in the casing as at 18 and is adapted to be moved into engagement with the said notch by a button li'vthe shank of which Works in a curved slot 17h in one end of the casing. A bell crank 2li ment with the keeper and to hold the bell crank, which is connected to the bolt in such position that the arm 24a thereof is depressed so that said arm by depressing the inner end of the 'lever 25 elevates the hooked end 2'? thereof. When an article oi" clothing or other article is placed on the hook, .its

Weight causes the outer end of the hook lever to descend and the inner end of said lever to rise and the ascending movement of the inner end of the lever by the engagement of said lever with the arm 24 of the bell crank partly turns the bell crank so as m to cause the link 23 to move the bolt 11 to locked position in engagement with the keeper against the tension orn the spring 13. Hence, the door continues to be locked from the inside as long as the hook is in use but when the article or articles is removed from the hook, thespring thereupon releases the ing manually on the outer end of the bolt rod so as to shoot the bolt against the tension of the spring and the bolt can then be secured in locked position by engaging the dog with the notch thereof as hereinbefore described. Hence, the lock may be operated either automatically by adding clothing on the hook lever or manually by means of the bolt rod.

The keeper may be of any suitable construction and the form, proportion and oonstl'uction of the several parts of lmy improved lock may be modied without departing from the spirit of my invent-ion and Within the scope of the appended claims.

lll-claim:-

l. In a lock of the class described, a casing, a bolt mounted for longitudinal movement' in the casing, a spring to normally hold the bolt in retracted. position, a bell crank pivotally mounted in the casing, a

' link connecting one arm of the bell crank to the bolt, and a lever pivotally mounted in the casing, extending outwardly therefrom and also having an inwardly extend- Macnee link connecting one arm of the bell crank to the bolt, a lever also pivotally mounted in the casinghaving an outwardly extending hooked end and also having an inwardly eX- tending arm, the latter being adapted to engage the other arm of the bell crank and to coact with thevbell crank to move the bolt to closed position against the tension of the spring whenthe outer end of the lever is depressed, and a dog mounted in the casing and adapted to be moved into engagement with the notch of the bolt rod to lock the bolt in such locking position.

In testimony whereof I affix my signature in presence of two witnesses.
